The Cohu 7100 Series camera becomes operational once it is:
1. Connected to an Ethernet network using twisted-pair Ethernet cable
2. Connected to its power supply and plugged into an ordinary electrical outlet
3. Assigned an IP Address
Note: If the camera is installed on a network that uses a DHCP server to assign IP
addresses the DHCP feature should be enabled in the camera. See RARP/DHCP/BOOTP
in Section 4.2 for more information.
Once an IP address is assigned to the camera the camera is accessed from a web browser by
typing the IP address into the browser s URL/Location field.
8 of 60

After entering the IP address into the browser the camera's View Images page will appear and
look similar to the following:
The camera's home page allows viewing live images accessing still images and navigating to
the browser-based configuration pages.
1.5 Configuration Basics
Once the camera is properly installed several features can be customized including image
settings security features and networking capabilities. While some of the camera's features will
need to be customized only for particular situations other features will need to be configured for
all installations. These important features can be configured using the browser-based
configuration page and are discussed in the following places in this manual:
Clock see the Set Date section in Section 2.4.4
Login and privileged passwords see Management Passwords in Section 5.2.2
The network gateway see TCP/IP Gateway section in Section 2.4.4
Image lighting see Lighting in Section 3.3
Use the camera's browser-based configuration pages to adjust the features mentioned above.
1.5.1 Browser-Based Settings Pages
The 7100 Series camera include browser-based settings pages for configuring most settings. The
pull-down menus and text input fields on these pages allow performance optimization of the
camera. When using the pull-down menus settings will activate when a setting is selected. For
the text input areas settings will activate when <Tab> is pressed.
9 of 60

To adjust the settings on the browser-based settings pages:
1. Become the privileged user by entering the correct username and password which will be
required when changing camera settings (see Passwords Section 5.2.2).
Note: Factory Default Username = root Factory Default Password = system
2. Choose the desired setting to be adjusted.
3. Select the appropriate value from the pull-down menu or enter the appropriate value into
the form field and then press <Tab>.
4. Repeat this process for other settings.
5. Press the Logout Session button or Exit the browser when finished.
Both of these actions will close that privileged session.
Note: For the browser-based pages to operate properly both Java and JavaScript must be
enabled. Review the browser help pages for details on setting up Java.
1.5.2 Online Help Pages
All settings on the browser-based settings page are linked to a comprehensive help file. Access
the help text for a particular setting by clicking the question mark icon that appears next to the
desired setting:
1.6 Lens Mount Compatibility
The Cohu 7100 Series cameras include a standard CS-mount and a C mount adapter.
Each lens must be mounted the distance from the camera's imaging chip. If the lens is not placed
at the proper distance it will not be possible to focus the lens. For more information about lens
selection and usage see the Lenses in Section 11.
1.7 Browser Compatibility
The Cohu 7100 camera supports most of the commonly used Web browsers on PC Macintosh
and UNIX/Linux platforms. The supported browsers are:
Netscape 4.67 and higher on a PC Macintosh or UNIX/Linux machine
Internet Explorer 5.5 and higher on a PC or Macintosh machine
10 of 60

The camera's configuration pages and other features are optimized for more recent browser
versions.
Improved performance of the camera can be accomplished by taking the following steps in the
browser:
Refresh/Reload the Page Liberal use of Refresh/Reload will generally clear up any
occasional display issues. If the Refresh/Reload button does not
appear to update the page it may help to request all new
information from the camera by forcing a reload from the server:
hold down the <Control> key (Internet Explorer) or <Shift> key
(Netscape) and click the Refresh/Reload button.
Clear the Cache The cache stores pages and images on the local computer so that
the browser can re-draw a screen or re-load a page quickly.
However the data in the cache is usually old. The forced reload
mentioned above should clear the cache. The cache can also be
cleared by turning caching off or dumping the cache contents via
the browser s Preferences dialog.
Enable Java Java must be enabled to manage the camera. The first time Java is
needed Java will take a few seconds to load.
Enable Cookies The camera uses cookies to secure the password protected areas.
Cookies are a mechanism that allows a web server to transfer and
store information on a user's computer. When users log in the
7100 gives a cookie to the computer so it can recognize a camera
manager. This cookie is automatically removed when a user selects
'logout' or quits the browser. The cookie also times out after a short
inactive period. Cookies are permanently enabled in Internet
Explorer. To enable them in Netscape go to the Edit menu select
Preferences and then go to the Advanced area.

2.0 Installation & Initial Configuration
2.1 Overview
This chapter discusses the installation procedures for the Cohu 7100 Series camera.
To install the camera:
1. Connect Ethernet and Power
2. Assign a valid IP address
3. Go through basic configuration
After these steps the camera should be ready to serve high-quality images to network users.
Further configuration topics are covered in later sections.
2.2 Connectors
The back of the camera contains the ports needed for installation: the Ethernet port and the
Power Input. The two LEDs on the rear cap will verify that the camera is successfully
connected: The Green Status LED will flash after power is connected and the Yellow Link &
Activity LED will flash to indicate network activity.
The camera's hardware address which appears on the label affixed to the back of the camera
should be handy when ready to assign an IP address.
The cameras may have other inputs depending on options. Refer to Section 1.3 or the Pinouts
appendix for information on how to use these ports.
2.2.1 Connect Ethernet
1. Connect one end of a twisted pair Ethernet cable to a network device
2. Connect the other end to the camera's RJ45 Ethernet Port
2.2.2 Connect Power
1. Use the mating connector that came with the camera and connect it to the power supply output
wires. The polarity is not important.
Note: When connecting the camera be sure to use the power adapter that came with the camera.
Please contact Cohu if a different power source is required.
2. Plug the mating connector to the back of the camera.
3. Plug the adapter into a standard power outlet (115vac).
Note: The camera automatically turns on once power is applied. The Green Status
LED on the back of the camera will flash.

2.3 Assign the IP Address
There are two basic methods to assign the IP address: DHCP or a directed ping packet. Another
method is available for advanced users by using Telnet or HyperTerminal. This information is
available in the Cohu 7100 Series Reference Manual.
2.3.1 DHCP
If the camera sits on a network that has a DHCP server the camera can get its address from that
server. This feature can be used to have the camera email the administrator with the dynamic IP
address it receives from a DHCP server.
When using the DHCP method the server will provide the camera with an unused address
automatically when the camera is powered up or rebooted. While this is a convenient method to
assign IP addresses it requires that the camera's addresses be tracked each time they are powered
down or rebooted. Cohu recommends using static addresses by sending a “Ping” message to the
camera. See note below.
Note: It is recommended to configure the camera with a “Static” address. In this way each
camera will always have the same address which will simplify selection of cameras.
However if the camera is on a controlled Network the LAN administrator must be
informed of this requirement so that they can assign the IP number for each camera. Each
camera will then be set up with the assigned (and unique) IP number. For more
information consult with the system administrator or refer to the documentation that
accompanied the DHCP server. Also refer to the Cohu 7100 Reference Manual for more
details.
2.3.2 Directed Ping Packet
To assign a static IP address to the Cohu 7100 Series camera a directed ping packet is
transmitted to the camera's MAC address using “MS DOS Prompt” program.
1. Choose an IP address that is not currently being used by another device on the network. If
necessary ask the system administrator for an available IP addresses.
2. Enter the ARP command at the command prompt. An ARP command consists of:
The camera's hardware address (see label on the back of the camera)
The desired IP address for the camera
Format: arp -s <IP Address> <Hardware Address>
Example:
14 of 60

Note: For ARP/Ping to work properly on Windows machines there must be at least one IP
address in the ARP table. Type ARP -A at the DOS prompt to ensure that one entry is
present. If there is not another IP Address in the table ping a known device on the
network to build an entry (See step 3 below). Once an entry is established in the ARP
table repeat the process to set the IP address for the camera.
3. Ping the camera s IP address. The camera must be fully booted to accept the ping. Once the
camera has received a ping packet it will use that IP address.
The camera's new IP can now be entered in the web browser Location/ URL field and finish
configuring it via the browser-based settings pages.
2.4 Configure the Camera
The cameras feature a browser-based installation wizard that contains all of the initial settings
that should be configured for each installed camera. After assigning an IP address to the camera
use a web browser to open the first page of the wizard. The installation wizard can also be
accessed by selecting Install Wizard from the navigational pull-down menu that appears on the
View Images page.
Note: For the browser-based pages to operate properly on Netscape browsers both Java and
JavaScript must be enabled. Go to the Edit menu select Preferences and scroll to the
Advanced section. Enable Java and JavaScript by clicking the appropriate check boxes.
Use the text input fields and pull-down menus in the installation wizard page to adjust the
camera's initial configuration settings. When using the pull-down menus settings will activate
when a selection is made. For the text input areas settings will activate when <Tab> is pressed.
To adjust the settings using the wizard:
1. Choose the setting requiring adjustment.
2. Select the appropriate value from the pull-down menu or enter the appropriate
value into the form field and press <Tab>.
3. Repeat this process for any other settings.
15 of 60

2.4.1 Focus
If the camera is out of focus the rapidly updating image on the first page of the wizard can be
used to help bring the camera into focus. The image that appears on the page is a reduced image
from the center of the camera's field of view.
The image on the Focus page displays a number that corresponds to the level of focus. Maximize
this number to properly focus the camera. As proper focus is approached either by bringing the
image into focus or by maximizing the focus number additional slight adjustments will bring the
camera into focus.
Note: The focus utility relies on sharp edges in the scene. If possible make sure the
camera is viewing something in the field of view with sharp edges.
To focus the camera slowly rotate the lens while you watch the updating image. For Micro-
mount lenses turn the entire lens. For C-mount and CS-mount lenses the lens usually contains a
built in focus ring on the outer edge of the lens.
When satisfied with the camera's focus click the Next>> link that appears near the bottom of the
page.
2.4.2 Image Size and Orientation
Use the second step of the installation wizard to personalize the size of the image to properly
position the camera so that it provides the desired field of view and to optimize the
characteristics of image.
16 of 60

The image that appears on this page is a half size image that updates more rapidly than a full size
image. Watch this image when positioning and framing the image. Use the settings on this page
to finalize the general characteristics of the image.
crop Cropping an image involves selecting one region of interest in the
image and discarding the rest creating a smaller image. When the
image is cropped rate at which the camera can process and
transmit images will increase. Set the cropping of the camera's
image by using the crop tool.
To set a crop area:
1. Click the Crop rectangle select button.
2. Click the part of the image that is to be in the upper-left corner
of the crop window. Do not hold the mouse button down.
3. Move the mouse to the area that is to be the lower-right corner
of the crop window and click again.
image size Select the factor to down-sample the image (or shrink). For
example selecting 1/3 will down-sample the image to 1/3 its
original size. Since smaller images are processed and transmitted
faster this feature is important if transmitting more images per
second is needed and less concerned with the quality of the
images.
flip/rotate Select a flip or rotate setting to properly orient the camera's image.
The default orientation is when the mounting screw hole is facing
down. The Horizontal and Vertical settings reflect the camera's
image. BLTR reflects the image across a diagonal line starting in
the bottom left corner of the image and extending to the top right
corner. TLBR reflects across the diagonal extending from the top
left corner to the bottom right corner. The 90 270 BLTR and
TLBR settings require additional processing which may slow
down performance. When satisfied with the image position and
size click the Next>> link that appears near the bottom of the
page.
2.4.3 Image Settings
The Image settings page provides the most important settings for optimizing the quality of the
camera's images.
17 of 60

The settings on the Image Settings page of the installation wizard include:
lighting Choose the type of lighting that illuminates the camera's
surroundings which determines the color corrections that are
needed to account for specific types of lighting. Each category of
lighting correction will change the basic color matrix the camera
uses to process its images.
brightness Set an average value for the overall brightness (gain) control. The
value of the brightness corresponds to the shade of gray of the gain
correction (For example 0.4 = 40% gray. The resulting image will
have an average brightness that is 40% white). Select the value by
clicking the Up or Down buttons or by entering a number into the
text input field. Return to the default brightness by clicking the
Default button.
contrast Adjust the midtones or gray levels of the camera's image. The
effect is to make the lighter and darker parts of the image either
more (up) or less (down) distinguishable from one another. Select
the value by clicking the Up or Down buttons or by entering a
number into the text input field. Return to the default contrast by
clicking the Default button.
compression Select the level of compression to apply to the image which
affects the quality of the image. Low levels of compression result
in high quality images large file sizes and slow transmission
times. Conversely high levels of compression yield smaller file
sizes poorer image quality and faster transmission times. Ideal
compression setting will depend on the minimum image quality
and maximum transmission time that is acceptable.
subject Select the appropriate shutter speed and light conditions to
improve the quality of the images. Choose the settings based on the
activity of the subject in the image and the level of illumination in
the camera's surroundings. Click the Next>> (link button).
18 of 60

2.4.4 Server Settings
The final step on the installation wizard contains the most important of the server settings. If
necessary consult the network administrator or ISP service for the appropriate information.
Use the text input fields and pull-down menus on this page to adjust the camera s necessary
server settings. All settings will be activated once a setting is selected.
name Enter a descriptive name for the camera (or leave as default) up to
16 characters long. The name can include numbers and letters. Use
the underscore character (_) instead of any spaces.
TCP/IP gateway Enter the IP address of the router to be used as a TCP/IP gateway
between networks. Traffic destined for another network will be
routed to the gateway and then forwarded to their destination. If
the camera will be used only over a local network no gateway
setting is required. However to access the camera on the Internet
an appropriate TCP/IP gateway must be entered.
time zone Choose the appropriate time zone setting from the settings
contained in the pull-down menu. The camera's clock is
preconfigured. Only the time zone setting is required for the
camera to display the proper time.
Note: The camera will use the time zone setting to properly adjust time-based
information it later receives from the network. Most of this time information is
sent using GMT a format that does not contain a time zone setting. The camera
will operate better if the time zone is properly configured.
set date Sets the date of the camera. This setting is important when
transferring images to a remote FTP server at which time the
default settings will use the date to create a file. Enter the
date in the MM/DD/YY format.
19 of 60

set time Sets the time of the camera. The time should be entered in 24-hour
format as HH:MM:SS (for example 20 seconds past 3:15 PM
would be 15:15:20). Before adjusting the clock make sure that the
correct time zone is set.
Note: A network timeserver can be used to keep time for the camera. See the Cohu 7100
Reference Manual for more information.
After completing the settings on the Server Settings page the installation wizard is finished.
Click the Done>> link that appears near the bottom of the page to access the camera's Live
Images page.
2.5 Access the Camera
To access the camera after the previous steps have been completed:
1. End any previous web sessions with the camera by closing the browser windows or exiting.
2. Open a new web browser session.
3. Type the camera's IP address into the browser's URL/Location field.
Note: You can add this camera to your host table to associate a text name with the IP address.
When the camera is in the host table it can be accessed by typing the name in the web
browser instead of typing the IP address. Consult the LAN system administrator for
details about this process.
4. Press Return.
The camera's View Images page appears. This page contains the live images from the camera
along with the digital pan/tilt/zoom controls. The web page should look similar to the following:
